How do you describe a reaction?

Last Updated: 19th January, 2020

A reaction is an action taken in response tosomething. If you're telling your parents that you want to moveout, you'll see by their reaction that they're sad about it.A reaction is often a physical in nature. A chemicalreaction describes the way a chemical behaves when combinedwith another substance.

Likewise, people ask, how do you describe a chemical reaction?

In a chemical change, the molecules in thereactants interact to form new substances. In a physicalchange, like a state change or dissolving, no newsubstance is formed. Explain that another way to say that noatoms are created or destroyed in a chemical reaction is tosay, “Mass is conserved.”

Beside above, what is a chemical reaction explain with an example? A chemical reaction happens when one or morechemicals are changed into one or more otherchemicals. Examples: iron and oxygen combining tomake rust. vinegar and baking soda combining to make sodiumacetate, carbon dioxide and water. things burning orexploding.

Keeping this in consideration, what is the definition of reactants in chemistry?

Reactants are substances initially present in achemical reaction that are consumed during the reaction tomake products.

What are causes of chemical reactions?

Let's start with the idea of a chemical reaction.Reactions occur when two or more molecules interact and themolecules change. Bonds between atoms are broken and createdto form new molecules. That's it.

What triggers a chemical reaction?

When two molecules collide with the right orientationand sufficient force, a chemical reaction may result. Notall collisions cause reactions, however; the atoms ormolecules must be able to recombine to form new compounds. Breakingbonds between atoms takes up energy, while forming new bondsreleases energy.

What is a chemical reaction in biology?

What is an example of a chemical reaction?

Combustion reactions, such as a burning candle,are also examples of the chemical change through thecombination of wax and oxygen in a reaction that producesheat, light, and carbon dioxide. Decomposition, the opposite ofcombination, occurs when a single substance breaks down into two ormore different substances.

How do you know when a chemical reaction has occurred?

Yes; new substances formed, as evidenced by the colorchanges and bubbles. Some signs of a chemical changeare a change in color and the formation of bubbles. The fiveconditions of chemical change: color chage, formation of aprecipitate, formation of a gas, odor change, temperaturechange.

What are three facts about chemical reactions?

They also release spectacular heat, light, and noise.Chemical changes produce new materials. They also usuallygive out or take in energy such as heat or light becausechemical bonds have been broken and made. When iron rusts,it reacts with oxygen in water or in air to create a new compoundcalled iron oxide (rust).

Why are chemical reactions important?

Bonds between atoms in molecules break and are reformedin new ways. Chemical reactions are at the heart ofliterally every biological process in the universe. Stars formbecause of chemical reactions; our sun ignited because ofchemical reactions in its core. Life developed on Earth as aresult of chemical reactions.

What is an example of reactant?

Under the proper conditions, such as temperature, time,or pressure, the chemical bonds of the reactants are broken,and the atoms form new bonds that give different combinations. Thesubstances that result from this recombination of atoms are calledthe products of the reaction. Example- NH3 + HCL →NH4Cl.

What is the definition of precipitate in chemistry?

In chemistry, a precipitate is aninsoluble solid that emerges from a liquid solution. The emergenceof the insoluble solid from solution is calledprecipitation. Often the precipitate emerges as asuspension. Precipitates can form when two soluble saltsreact in solution to form one or more insolubleproducts.

What is chemical equation in simple words?

In chemistry, a word equation is achemical reaction expressed in words rather thanchemical formulas. A word equation should state thereactants (starting materials), products (ending materials), anddirection of the reaction in a form that could be used towrite a chemical equation.
